Envoys from the Stars

Three first-born children are sired by three males from Earth's three great races! Each of these fathers had suffered abduction and bio-genetic surgery by extraterrestrials who appear to be a mix of ancient ancestors to our planet's contemporary peoples.
In the interest of Earth's mankind, our progress over thousands of years, has been monitored, believe or not, on a regular basis by these ancient ancestors, but while consistently being horrified by the advent of our countless wars, our advancing technologies, in the alien's minds, have now deemed us to now be approaching the point of starting wars which could result in our total annihilation!
Each child, Charles, Chein, and Zuda, has been born with highly advanced alien genes which are programmed to advance in stages towards their maturation whereby they finally will be able to report collectively & accurately at any point whereby mankind's manifest destiny could be ultimately affected! Hence the possibility of an alien intervention!
